BOAT STEERING AND BEVERSING- GEAR.

Specification of Letters Patent.

Patented Sept. 9, 1919.

Application filed Mag '13, 1919. Serial No. 296,88 i.

To all whom it may concern:

Be it known that I, J one: Grnonen AuLsn- BROOK KITOHEN, of 7 Rose Bank,Scotforth, Lancaster, in the county of Lancaster, En land, a subject ofthe King of Great Brltaln and Ireland, have invented certain new anduseful Improvements in Boat Steerln and Reversing Gears, of which thefollowing 1s a specification.

This invention relates to boat steeringand reversing gear of thetypesuch as descrlbed in prior Patent No. 1,186,210, in which tworudders are so arranged that they deflect or reverse the stream of waterdriven astern by the propeller in order to efiect steering and reversalof the boat without varyingthe speed or the direction of rotation of thepropellers.

The object of the present invention 1s to provide a compact and simpleform of gear having a minimum of joints or connections in which lostmotion can occur and capable of being operated by hand or by power tosuit requirements.

The invention comprises the combination with a sector or its equivalentupon each rudder stock, of chains or like flexible connections attachedto such sector at the opposite ends of its circular face and in oppositedirections to an operatlng pulley or its equivalent, the two flexibleconnections of each sector passing over separate gu de or jockey pulleyscarried by a slide, with means for traversing the slides simultaneouslyin opposite directions, for the purpose described. j

Referring to the accompanying explanatory drawings Figure l is a planview, Fig. 2 a sectlonal elevation, Fig. 3 a frontelevation, Flg. 4t anend view looking from left to right of Fws. 1 and 3, with certain partsomitted, and Flg. 5 an end view looking from right to left of Figs. 1and 3 with certain parts omitted, of a rudder control gear constructedin one convenient form in accordance with my in vention. p

Fig. 6 is a diagram to illustrate the action of the gear. it

Fig. 7 is a diagrammatic perspectlve view of slides 0, p.

of rudders arranged in one convenient form for csontrol bythe gearillustrated in Figs.

to A

F igs. 8 and 9 illustrate in Ian and front elevation respectively a modied application of the invention. Figs. 10, 11 and 12 illustrate indiagram form a further modified application of the invention. p i

The same reference letters in the different views indicate the same orsimilar parts.

The rudders a, b are mounted on a concentric sleeveand spindle 0, clforming rudder stocks, 1 and to the upper end of the spindle is fixed asector e, while a similar sector f is mounted onthe sleeve ,0. Eachsector has two grooves g, h in its circular face which serve to receivethe guide chains, wire ropes or like flexible connections 71 (showndiagrammatically in Figs. 1 and 6) which are secured to each end of thecircular faces of the sector so that the chains or ropes pass inopposite directions therearound. The other ends of each of the twochains or ropes, or if a single chain or rope be used for each sector,the center portion of the same, are or is secured to a drum or pulleyjwhich may be rotated by hand through the medium of a tiller bar or itsequivalent, or by power in any convenient manner.

When two chains or ropes are used, they wind around the drum or pulleyin opposite directions, that is to say while one chain or rope is beingwound on the drum or pulley,

the other one is being paid out. Similarly if a single chain is attachedto the drum, one end is drawn in and the other paid out.

There are two drums or pulleys j, 70 or double drum surfaces for eachsector.

The two chains or ropes before referred to for each rudder stock sector6, fpass around guide pulleys m, n, upon the opposite ends through equaldistances in opposite directions by a right and left hand screwedspindle g which may be rotated by hand or by power in any convenientmanner and which passes through nut-like parts 9, .9, one upon eachslide. 1

The latter are traversed guide pulleys, m,n in opposite directions, re-

sulting in the sectors- 0, 7 being rotated through equal angles inopposite directlons. The drums j, k may be rotatedsimultaneously with orafter the movement of the screwed spindle Q is completed, in order toeffect steering of the boat while it is moving astern. r

7 By the arrangement of the guide pulleys m and 11.,it will be seen thatthe movement given to each sector is twice that given to its slide, sothat a relatively narrow operating gear only is required to give theangular movements necessary to the rudders to control the boat in itsdirection of travel.

The arrangement of the slides a, p with guide pulleys m, a, provides arapid means for moving the sectors 6, f in opposite directions for boatsteering or speed variation purposes.

Instead of operating the slides 0, p by a right and left hand screwedspindle, we

may operate them by a pinion u (see Figs.

8 and 9) engaging two racks '2), w one upon each side.

In the arrangement shown in Figs. 10, 11 and 12, the pulleys m, n whichserve to deflect the chains or the like '5 so as to move the sectors inopposite angular directions,

are operated by the links m from the lever y which is itself actuated bythe hand lever the left hand ends of the sectors.

2. Figs. 11 and 12 show the arrangement of the two chains or the likeleadin from it 4, 4 there are two superposed pulleys while the pulleys 5are all single pulleys. A similar dispositionof parts is provided forthe fchains or the like from the right hand ends of the two sectors. Inthis example, superposed pulleys m, a are mounted upon each "slide,instead of two single pulleys at opp0- site ends of the slides as in theprevious examples. V

I may vary the details of my improved gear to suit any particularservices or requirements.

Havingnow described my invention, what I claim as new and desire tosecure by Letters Patent is 7 1. In boat steering and reversing gear,

two cooperatingrudders with rudder stocks, "a part upon each rudderstock,- rotatable means, two flexible connections between the 'a slide,as set forth.

tween the rotatable element and the two ends of each sector, and meansdeflecting simultaneously each pair of flexible connections, as setforth.

3. In boat steering and reversing gear, in combination, two cooperatingrudders, concentric rudder stocks for the said rudders, a sector uponeach rudder stock, a rotatable element, flexible connections between therotatable element and the opposite ends of each sector, and meansdeflecting simultaneously each pair of flexible connections, as setforth.

4. In boat steering and reversing gear, in comblnation, two cooperatingrudders with rudder stocks, a part upon each rudder stock, rotatablepulleys, two flexible connections between said pulleys and each partupon a rudder stock, and two pulleys deflecting simultaneously each pairof flexible connections, as set forth.

5. In boat steering and reversing gear, in comb nation, two cooperatingrudders, concentric rudder stocks for the said rudders, a sector uponeach rudder stock, rotatable pulleys, two flexible connections betweensaid pulleys and the opposite ends of each sector, and two pulleysdeflecting simultaneously each pair of flexible connections, as setforth.

6. In boat steering and reversing gear, in combination two cooperatingrudders with rudder stocks, a part upon each rudder stock, rotatablemeans, two flexible connections between the rotatable means and eachpart upon a rudder stock, two slides, two pulleys upon each slide, meanstraversing the slides simultaneously in opposite directions, the twoflexible connections of each part upon a rudder stock passing around andbeing deflected by the two pulleys upon I 7. In boat steering andreversing gear, in

combination, two cooperating rudders, concentric rudder stocks for thesaid rudders, a

sector upon each rudder stock, a rotatable part, flexible connectionsbetween the r0tatable part and the opposite ends of each sector, twoslides, two pulleys upon each slide, means traversing the slidessimultaneously in opposite directions, the two flexible connections fromeach sector passing around and being deflected by the two pulleys upon aslide, as set forth.

8. In boat steering and reversing gear, in combination, two cooperatingrudders, concentric rudder stocks for the said rudders,

a sector upon each rudder stock, a rotatable part, flexible connectionsbetween said rotatable part and the opposite ends of each sector, twoslides, nut-like parts upon each slide, a right and left hand screwedspindle passing through said nuts to traverse the slides simultaneouslyin opposite directions,

the two flexible connections from each sector passing around and beingdeflected by the two pulle s upon a slide, as set forth.

In testimony whereof I have signed my name to this specification.
